# Install Impeccable in Google Antigravity

Source: https://github.com/pbakaus/impeccable
Listing: https://www.antigravityskills.org/skill/impeccable
Safety review (2026-10-14): Well-documented design skill that runs a downloaded, checksum-verified engine binary, writes .impeccable/ files and contacts impeccable.style; set IMPECCABLE_NO_TELEMETRY=1 to skip the anonymous choice report.

## Rules for the agent
- Before running anything, tell the user what you will download and whether it contains scripts, and ask them to confirm.
- Install into this project (.agents/skills/) unless the user asks for a global install (~/.gemini/config/skills/).
- Do not run other commands from the source repository unless the user asks.

## Steps
1. Download the repository

```bash
git clone --depth 1 https://github.com/pbakaus/impeccable /tmp/impeccable
```

   The repository commits a prebuilt Antigravity copy of the skill at .agent/skills/impeccable (the folder we reviewed at 2f98774).
2. Copy the skill into this project (workspace skill)

```bash
mkdir -p .agent/skills && cp -r /tmp/impeccable/.agent/skills/impeccable .agent/skills/
```

   Run from your project root. The README (Google Antigravity section) uses .agent/ for project installs, and this build's SKILL.md allows and calls .agent/skills/impeccable/scripts/impeccable, so use .agent/skills/, not .agents/skills/. docs/HARNESSES.md says Antigravity also reads .agents/skills/ but that copy would not match the paths inside SKILL.md.
3. Or install it for all projects (global skill)

```bash
mkdir -p ~/.gemini/config/skills && cp -r /tmp/impeccable/.agent/skills/impeccable ~/.gemini/config/skills/
```

   Global path from the README. For the Antigravity CLI the global folder is ~/.gemini/antigravity-cli/skills/.
4. Check that Antigravity sees it, then initialize
   Antigravity 2.0 app: start a new conversation and ask "What skills do you have?" (the app has no /skills command). Antigravity CLI: run /skills; in a session already open run /skills reload first. Then ask the agent to run /impeccable init in your project; the first launcher call downloads the engine, so allow network access when asked.

Note: One-command alternative: `npx impeccable install --providers=antigravity --scope=project` (or `--scope=global`); the engine source maps antigravity to .agent/ and the global scope to ~/.gemini/config/skills. The README's own provider examples do not name antigravity, only its manual copy section does. No API key is required; the first engine call needs network access to github.com unless the binary is already installed.

Done when the skill is listed: in the Antigravity 2.0 app ask "What skills do you have?" in a new conversation (the app has no /skills command); in the Antigravity CLI run /skills (run /skills reload first in a session that was already open).
